T-RIP is a PC/Windows based program. Mac users often wonder why there is no Mac version. The truth is while Mac computers are certainly widely used to create graphics – printer drivers are almost always PC based. This is just the way it has evolved and it is no reflection on graphics programs. There are some Mac RIP programs available that work on a native Mac operating system. T-RIP will work on a Mac using Windows emulation programs.
The problem is that to be able to print directly to T-RIP from a graphic program the user needs Windows versions of the graphic programs. In most cases a Mac user has Adobe Illustrator and/or Photoshop on the Mac side but don't have Windows versions because of the extra cost. Keep in mind that with the Creative Cloud you can now have Adobe Illustrator and Photoshop on "two" computers – and they can be Mac or PC. That means you could install the PC version of these programs on your Mac in the Windows emulation version.
If you don't have a Windows version of the graphic program the artwork would need to be created on the Mac side and then the file saved in a format that is T-RIP friendly. Windows would need to be opened on the Mac and T-RIP launched and the file simply imported into T-RIP for printing.
T-RIP allows you to ONLY import the file formats of .AI, .EPS, .PS and .PDF.
Here are some easy steps:
If the file is simply a one color file – create the graphic in a graphic program like Adobe Illustrator or Photoshop. Save or Export the file in one of supported formats. Change to Windows on a Mac. Open T-RIP from the T-RIP icon. Go to File/Import and import the image. Print. Easy. (Note: make sure to set the halftone LPI, angle and dot shape from Queue/Properties/Print Mode Overrides/Halftones – for the color of Black only. Make sure to uncheck Enable Application Halftoning.)
If you create a typical "channel" separation in Photoshop there are certain requirements that you need to follow. You can create channel separations manually or you can use programs like T-Seps. Normally a channel separation in Photoshop is made from an RGB file. If using a program like T-Seps a Shirt channel is also created so you can visualilze how the file will look on different shirt colors. The "problem" is that the RGB channel and shirt color channel don't need to print and it can get confusing.
Here are simple steps:
1. Create the channel separations manually or with an automated program like T-Seps.
3. Go to File/Save As and choose DCS 2.0 EPS as the format. Make sure Spot Color is checked.
4. When you get the DCS Format window select Single File Color Composite. Don't worry about any of the check boxes.
5. Open T-RIP. Go to File/Import. Import the file. You will normally get a Page Manager window showing small thumbnails of each page. Select All of these (by default) and click on Apply. The file will now be imported into T-RIP with one "page" for each channel. Each new page will retain the "channel header" information you used when you were in Photoshop.
6. Once the file is imported and a preview is generated – click on the file name in the Name window. In the lower right of the screen you will now see a drop down box showing all of the individual separations. Select the one you want to print and click on the colorful Printer icon along the top menu header. Do this for each file.
Printing Spot Color Separations in Adobe Illustrator
You can create color separations in Adobe Illustrator. Remember that each color must be a Pantone Spot Color in order for the separation to print correctly. If you go to File/Print and only see CMYK listed as the colors then your file is not "separated" into specific spot colors.
Here is how to print from Adobe Illustrator:
1. Go to File/Print. Select Output from the left side window.
2. In the Printer window select Adobe Postscript File and in the PPD window select Adobe PDF.
3. Under Output/Mode select Separations (Host Based).
4. Make sure the page size is correct and that the image fits on the page.
5. Select Marks and other options that you would normally select when printing from AI.
6. Unselect a Printer Icon from any seps you don't want to print. By default Adobe always thinks you want a CMYK file so uncheck these.
7. Set the halftone LPI, dot shape and frequency.
8. Select DONE and make sure the file has an extension of PS. This stands for Postscript and is a format that T-RIP will open as a separated file.
9. Import the file into T-RIP – just like in steps 6 for printing a Photoshop separation.
Good luck with this. It may sound hard but once you have done a couple of jobs it is very easy.
